Oil-Immersed Power Transformer with On-Load Tap Changer
Product Description
The SZ11, SZ13, and SZ20 series on load tap changer oil immersed power transformers are power transformers that can regulate voltage under load conditions. They are upgraded products developed based on the S11 series oil immersed power transformers.
The voltage level is 35kV and below, and the product capacity range is 200-3150kVA.
It is suitable for areas with large and frequent voltage fluctuations in the power grid, enterprises, or places with stable voltage requirements.
Features:
The on load switch can be operated automatically or manually under load, or through a remote voltage regulator controller to achieve voltage regulation
Adopting a new oil passage structure, high heat dissipation efficiency, reducing transformer temperature rise, and extending product service life
Design of pressure relief valve protection device to prevent transformer damage caused by high fault pressure
Temperature inspection protection device to prevent transformer damage caused by high temperature.
